Telomere findings may offer insights

A new study shows that an enzyme called PARP1 is involved in repair of telomeres – the lengths of DNA that protect the tips of chromosomes – and that impairing this process can lead to telomere shortening and genomic instability that can cause cancer.

Beyond SARS-COV-2

Dr Jennifer Cane, a Postdoctoral Research Assistant, asks what sequencing respiratory viruses can tell us.

Microsatellite instability cancer tests

New US research compares the data of newly diagnosed cancer patients who received two different types of tests to determine their course of treatment.

Novel genetic variants associated with Alzheimer’s disease

New research has identified several genetic variants that may influence Alzheimer’s disease risk, putting researchers one step closer to uncovering biological pathways to target for future treatment and prevention.

Bat swarming and immunity

Bats carry some of the deadliest zoonotic diseases that can infect both humans and animals, such as Ebola and COVID-19.

Fibroblast cells and pancreatic cancer growth

Older people may be at greater risk of developing pancreatic cancer and have poorer prognoses because of age-related changes in cells in the pancreas called fibroblasts, it is claimed.

Pores for thought

A team from Nottingham looks at intraoperative molecular diagnosis of brain tumours using nanopore sequencing.

Activating genes using CRISPR technology

There are over 7000 different rare genetic diseases, and often it can be a significant challenge and take a long time to receive a correct diagnosis.

The search for genes that cause diseases

A new statistical tool developed by researchers at the University of Chicago improves the ability to find genetic variants that cause disease.

Figuring out the threats: Problem-solving with genomics

As the COVID-19 enquiry continues to unpick the tangled threads of the pandemic response, little has been said about one of the most effective weapons against the SARS-Cov-2 virus – pathogen genomics.

Breast cancer cells’ self-sacrifice is potential cause of relapse

For patients with early-stage breast cancer, there is a 7% to 11% chance of relapse within five years after receiving initial treatment.
